ci: add arm64 go builds and docker images

[fmarani]

Hopefully this PR should be enough to get the project deployable on arm64 machines.

These are the action results on my fork (see here):

I have not tested the release workflows as they required a bit more work. I am trusting the docker_manifest section works as is.

Its very useful for Amazon EKS Auto mode, that support ARM64 nodes via built-in System Node Pool.
@clementnuss Are there any plans to merge this into main?
